If you need the "Use different join port" functionality working, you can use the following beta version of IGOR. Use it on the server side.

It looks like this could be what I need. I will have a go at it the next days.
I have never heard of that beta version of iGOR.
Thx for posting Jackseller.

I need to host on 2 server behind my router.
So I need different GPL ports and my router has to forward these different ports to the 2 server with a specific IP adress in my home network.
Any help would be much apreciated.

Well, that actually works. I have 3 Hauls servers up on iGOR. Hauls1 is running my hacked ports. Hauls2 is standard ports. Hauls3 is the new iGORd, with ports just changed in the iGOR program.
It all works, 3 servers behind the same router, on the same IP address. Just different local address and ports.
Great stuff!
Where has this been hiding?

Unfortunately, this beta version doesn't help me. Unlike Vroc, it doesn't allow to change the host echo port. I host all my servers on the same PC (same local IP address). It works perfectly with Vroc for many years, but not really with iGOR (race list problems and crashes).
So i still use Vroc for my championship.

my router (AVM Fritzbox) does not allow me to add another IP with the same port

You can't do that, it's the basis of port forwarding. You can use same IP with different ports but not the reverse.

Warren, I wanted to ask you when I first saw it but then I forgot
Your server that host Riverside states as circuit "Rouen / Riverside International Raceway"; why is that?
